用c刷新excel文件，该文件从sqlserver获取数据

我一直在搜索c#的教程，以便在不打开excel并单击刷新按钮的情况下刷新excel文件。我找到了解决方案，而且非常简单。我想分享

private void ExcelRefresh(string Filename)
    {
        try
        {
            object NullValue = System.Reflection.Missing.Value;
            Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
            //excelApp.DisplayAlerts = false;
            Microsoft.Office.Interop.Excel.Workbook Workbook = excelApp.Workbooks.Open(
               Filename, NullValue, NullValue, NullValue, NullValue,
               NullValue, NullValue, NullValue, NullValue, NullValue,
               NullValue, NullValue, NullValue, NullValue, NullValue);
            Workbook.RefreshAll();
            System.Threading.Thread.Sleep(20000);
            Workbook.Save();
            Workbook.Close(false, Filename, null);
            excelApp.Quit();
            Workbook = null;
            System.Runtime.InteropServices.Marshal.ReleaseComObject(excelApp);
        }
        catch(Exception ex){
            MessageBox.Show(ex.Message);
        }
    }
    private void button1_Click(object sender, EventArgs e)
    {
        ExcelRefresh(@"D:'test.xlsx");
    }
